2 Claims.

This application is a division of applicants copending application for patent for Flange Oilers, filed June 10, 1947, Serial No. 753,772 Patented April 12, 1949, No. 2,467,119.

The invention relates to lubricating apparatus and has special reference to flange oilers for the wheels of railway vehicles and particularly to devices for feeding oil to the oiler shoes of such flange oilers, although its adaptability is not necessarily so limited.

In certain known types of flange oilers the oiler shoe which engages or bears upon the wheel flange is provided with an oil passage or bore through which the oil is fed from a suitable source, such as a measured feed device. to the wheel flange. In order to prevent clogging of this passage or bore there is provided for relatively free axial and lateral movement therein a solid rod or pin one end of which normally bears against the wheel flange, and the oil fed to the passage or bore of the oiler shoe may be conducted to the wheel flange not only along the wall of the passage or bore but also along the surface of the rod or pin.

This type of feeding apparatus has been found in practice not fully eflicient in maintaining a relatively unrestricted flow of oil to the wheel flange, and the object of the present invention is to provide an improved means for guarding against the clogging of the oil passage or bore and enhancing the operativeness of the oiler under both favorable and adverse conditions.

To this end the invention is directed to the provision of a tubular member within the oil passage or bore of the oiler shoe. such tubular member being of less outside diameter than the inside diameter of the passage or bore and being free for limited axial and lateral motion therein though preferably anchored against undesired separation therefrom.

In the accompanying drawing illustrating the invention, in the several figures of which like parts are similarly designated.

Fig. 1 is a side elevation illustrating a flange oiler embodying the invention, the same being shown in association with a wheel and including a fragment of an appropriate mounting bracket,

Fig. 2 is a front view of the flange oiler with a portion of the wheel with which it is associated shown in section, and

Fig. 3 is an enlarged axial sectional view of the oiler shoe in association with a wheel.

In the particular embodiment of flange oiler shown. and to which applicant's copending application above referred to relates, there is a mounting plate I with a pair of marginal guide strips 2 secured thereto in oifset spaced relation by end and intermediate bolts 3 and 4, respectively, with interposed spacing collars 5 and 6 and lock washers I where desired. The intermediate bolts 4 serve not only to complement the end bolts 3 in affixing the strips 2 to the mounting plate I but furnish a means for attaching the flange oiler as a whole to the mounting bracket 8, Fig. 1.

Positioned between the mounting plate I and the strips 2, and capable of limited sliding movement therebetween vertically, laterally and angularly, is a slide plate 9 having laterally offstanding pairs of guide arms II] which extend between adjacent portions of the mounting plate I and the guide strips 2 and serve not only to retain the slide plate in position but, to limit its movement relatively to the spacing collars 5 and 6. Adjacent to its lower end the slide plate 9 is provided with a bearing member I I into which is fitted the shank I2 of the oiler shoe I3, this shank being secured to the bearing member I I by bolting ears 14 carried by the shank and bolts I5 passing through these ears and threaded into the flanges is on the bearing member I0, lock washers Il preferably being provided to maintain a tight assembly.

By this arrangement it will be seen that the oiler shoe may readily be removed and restored or replaced, and due to the symmetrical arrangement of the bolting ears I 4 with respect to the axis of the shank I2 may be properly positioned for either right-hand or left-hand operation.

Moreover, the provision for vertical, lateral and angular movement of the slide plate 9, and with it of the oiler shoe l3, makes possible accommodation of the shoe to radial, axial and axiallyangular motion of the wheel l8 with the flange I9 of which the shoe is engaged.

As shown particularly in Fig. 3, the operative face of the oiler shoe is provided with a recess 20 substantially conforming in contour to the wheel flange I9 and flanked by guide yokes 2| and 22 at front and rear of the flange, respectively, the yoke 22 at the rear of the flange being made to extend well down radially of the wheel in order to guard against displacement of the shoe from the flange during movement of the wheel.

Interiorly of the shoe I3 and its shank I2 extends a bore 23 (Fig. 3) terminating at one end in the wheel flange engaging recess 20 and at its other end in a counterbore providing a threaded socket 24 to receive and retain the threaded end of a suitable flexible or jointed conduit 25.

Within the bore 23 is arranged a tubular feed member 26 of less external diameter than the internal diameter of the bore 23 with its lower end cut off at an angle in a plane tangent to the adjacent face of the Wheel flange. During operation of theoiler this end of the tubular feed member will wear So as to substantially conform to the face of the wheel flange, but it will be suspended in circumferentially spaced relation to the wall of the bore 23 and will be prevented from dropping out of the bore by retaining means such as a cross pin 21 or the like the'projecting" ends of which are normally spaced from but may bear against the shouldered inner extremity 28 of the threaded socket 24. Obviously, withthis mode of assembly of the feed member: 26'such'feed mem ber is permitted a limited movement within the bore 23.

This tubular feed member 26 has advantages over the solid rod type of feed members hereinbefore referred to as used in installationsxof this general character for the reason that oil from the conduit 25 may pass not onl along its outer surface and along the Wall of the bore, or between these surfaces, butmay pass also through or along the walls of its central tubular passage, thus guarding mor effectivel against clogging, it being understood that oil is ordinarily fed through the conduit 25 to the oiler shoe in small measured quantities and usually drop by drop.

Various changes and modifications are considered to be within the principle of the invention and the scope of the following claims.

What I claim is: i

1. In an oiler device, an oiler shoe for, cooperation with a part to be oiled and having. means for. connecting it to a source of oil, said shoe having an oil feeding passage extending therethrough from said connecting means to said part to be oiled, and a tubular feed member substantially equal in length to the length of said passage positioned within said passage and having an inlet end within said shoe adjacent to said connecting means and in open communication with the source of oil, and its tubular formation serving to provide with said connecting means a continuous oil passage between said source and the part to be oiled, said feed member being of less outside diameter than the diameter of the feeding passage of said shoe and thereby forming in association with the wall of said passage three normally concurrently functioning surfaces for directly conducting lubricant from said source to the part to beoiled.

2. An oiler device as claimed in claim 1, in which the oil feeding passage is counterbored and has a shoulder remot from the part to be lubricated engaged by the oiler shoe, and the tubular member is provided with retaining means arranged substantially normal to the axis of said passage, said retaining means extending radially beyond the periphery of said tubular member and in such proximity to the-walls of said counterbore as to maintain the tubular member in arrangement substantially coaxially of said passage.
